Redox flow batteries have gained significant interest as a large-scale energy storage device due to their benefits over other storage technologies, which include a high degree of safety, the ability to decouple power and energy, a long lifetime, potentially low capital costs, and/or high energy efficiency. Large quantities of electricity are capable of being stored utilizing redox flow battery technology. The acceptance of redox flow batteries and a broad range of energy storage applications is dependent on continued performance improvement, cost reductions, and long-term reliability over the lifespan of the system.
